Introduction 
This manual covers all three of the Harman 
Kardon TC Series amplifiers: the TC600, 
TC300, and TC304.  Because of their clean, 
powerful design, these amplifiers can be 
used full-range or in  specialized multi-amp 
systems as bass, midrange, or treble 
amplifiers. 
The TC600 and TC300 are two-channel 
(stereo) amplifiers that can be bridged into a 
single channel.  The TC304 is a four- 
channel amplifier that can be configured for 
four, three, or two discrete channels.  All of 
the TC Series amplifiers are capable of 
operating in  simultaneous stereo plus 
bridged mono mode, which allows for im- 
mense flexibility in system design and 
future upgrade potential. 
Please read this manual for information 
about system design considerations, 
connections, and operation.  Before you 
begin your installation, determine your 
speaker configuration, wiring route, and 
location of the amplifier(s).  Retain this 
manual for future reference. 
Important 
The TC Series amplifiers are professional- 
quality amplifiers that can be incorporated 
into any automotive system, from the 
simplest to the most complex.  We strongly 
recommend professional installation of your 
TC Series amplifier to ensure that you 
obtain the optimum performance from your 
entire system.
